First of all, we should arrange the time reasonably and grasp the best time for students, that is, the third minute to the twenty-fifth minute after class. During this period, it is necessary to make a breakthrough in the important and difficult points of teaching, so that students can truly understand and master the knowledge of a lesson. To this end, teachers need to do the following:

1. Prepare lessons carefully and prepare well for each class.

When preparing lessons, we should create some interesting and meaningful situations for students of different grades to stimulate students' interest, so that students can feel the real things with some practical things and things and avoid some illusions.

2. Choose some innovative classroom teaching methods.

Make good use of the functions of scientific and technological information and choose different teaching methods for different classes, so that students can feel refreshed every day, but we can't lose the traditional teaching mode. We should make good use of both. For example, in the course of teaching graphics, we can use food and the current multimedia teaching to completely abstract some geometric figures, so as to learn the characteristics and structures of these geometric figures, make abstract things concrete and simple, simplify problems, and make students easier to master.

Secondly, the design of math homework. Now the homework assigned by the teacher to the students can be summarized as "one more", "two false" and "three invalid" in the following words. That is, "one more" means that students have a large amount of homework. Students have to do many beautiful exercises in textbooks every day, and they are trapped in the sea of questions every day. "Two false" means that students are forced by teachers to copy other people's homework or blindly write something they don't know is right, so as to change the illusion of handing in homework on time; "Three ineffectiveness" means that students are exhausted all day when they write their homework and teachers evaluate their homework, but in the end they get twice the result with half the effort and have no effect. In view of this situation, I have the following ideas:

1. According to the situation of our own students, students with good ability can give their children "homework in advance", that is, let students preview in advance, have a general understanding of the knowledge of next semester, and then complete the corresponding exercises in the textbook in advance for students with strong ability, so that these students can finish some high marks relatively easily in class; For other students, teachers can make a preview outline for students at the weekend of each week, so that students can have a certain understanding of what they have learned, which can not only improve the quality of students' lectures, but also allow students to make arrangements for preview and review while easily completing their homework.

2. Carefully choose the homework questions that are most suitable for students. As teachers, we should choose the best and most representative exercises for our students according to the situation of our class. Because students can reflect on their learning of mathematics by doing problems and form different mathematical experiences and abilities, it is very important for students to do what kind of math problems, which can not only reflect teachers' teaching level, but also reflect teachers' teaching quality. In addition, doing more problems seriously can really improve students' math scores, but blindly relying on "sea tactics" is really a heavy burden for students, and most of them get twice the result with half the effort. Mathematics is an interlocking subject, step by step, so math homework should not be too excessive, nor too simple and familiar, so it must be carefully selected, so as to really reduce the burden.

3. Change the traditional way of judging homework and judge homework in an open way. For students, not all the questions left by teachers can be done, so we should give students the initiative to learn, let students boldly complete and put forward their own ideas, especially for the questions that can't be done, let students analyze the reasons why they can't do it and write them down under the corresponding topics, so that teachers can clearly see that students have not mastered those topics well in their homework and need further explanation; In addition, some students completed it with the help of their classmates, and asked them to write under the corresponding topic, which not only helped the teacher to check the students' homework in time and reflect the real situation; Finally, when the students finish their homework, ask them to write down what knowledge was used in today's homework to finish it. How do they feel about doing their homework today, and how do they feel about the completion of their homework today? In this way, students can not only summarize and sort out what they have learned, but also review. This not only lightens the burden, but also improves the learning quality and efficiency.

Finally, improve their own quality and teaching ability. As the saying goes, "Give a student a glass of water, and a teacher needs a bucket of water". As front-line teachers, we should keep learning, constantly "recharge" ourselves, and constantly learn those advanced concepts, so as to serve the students better, gain a firm foothold on our three-foot platform, and live up to our title of "the most glorious profession under the sun". Study hard, be a loyal friend of students and do well in every class.
